Northern Quoll (Dasyurus hallucatus) lives in australian grasslands across Northern Australia. It feeds on insects and small vertebrates. Its conservation status is Endangered.
Fascinating facts about the Northern Quoll
- Male northern quolls die after the breeding season, leaving only females to rear the young. In the wild males typically survive about one year, with the maximum recorded for a female at three years, and during the mating period they suffer severe weight loss, fur loss, parasite infestation, high testosterone and anaemia.
- When northern quolls are kept on predator-free islands they quickly lose their innate fear of native hunters. After just 13 generations of isolation, island-kept quolls no longer recognised or avoided dingoes and cats, predators they have co-evolved with.
- A single island refuge proved how fast a northern quoll population can expand when threats are removed. After being translocated to the toad-free English Company Islands in 2003, the quolls thrived and an estimate of 2 193 female individuals was recorded on Astell Island by 2014. This rapid growth demonstrates the potential of isolated safe habitats to boost numbers, offering a valuable tool for conserving the species amid widespread declines.
- When cane toads entered Kakadu, the toxin caused an immediate collapse of local quoll numbers: one monitoring site lost every individual, while another fell from 45 animals to just five. The toads are lethal because quolls are poisoned after eating or mouthing them, a danger that has driven rapid local extinctions.
- Across its historic range the northern quoll has lost about 60% of its occupied area, one of the steepest reductions among the nine species examined. This contraction was only surpassed by the decline of the brush-tailed rabbit-rat, highlighting the severity of the quoll's loss.

About the Northern Quoll
In the scorching deserts of northern Australia, a small, enigmatic hunter weaves through the spinifex grass, its large eyes gleaming like lanterns in the dark as the Northern Quoll pursues its nocturnal quest for insects and small vertebrates. With a lithe, almost serpentine motion, it navigates the rocky outcrops and sandy dunes, its long, pointed snout twitching as it sniffs out the faint scent of its prey. This elusive, endangered marsupial is a testament to the remarkable adaptability of life in the harsh, sun-baked landscapes of the Outback.
